Abstract
Method and apparatus for forming a disc drive actuator assembly. A rigid actuator arm formed of printed circuit board (PCB) material is configured for placement over a rotatable disc. A head-gimbal assembly (HGA) is provided comprising a data transducing head, a flexible suspension assembly and a conductor which is connected to the head and routed along the flexible suspension assembly. A Z-axis conductive adhesive film is used to mechanically and electrically connect the HGA with a distal end of the PCB actuator arm. The Z-axis conductive adhesive film is substantially conductive across the thickness of the film and is substantially nonconductive along the length and width of the film. In a preferred embodiment, the film establishes a grounding path to dissipate electrostatic charge in the HGA. In another embodiment, the film establishes a data signal path for the head.
